Key components of our Firewall Assessment
A structured, defined delivery model ensuring you receive actionable outputs and tangible improvements to your operational security posture. Built specifically for industrial automation and critical infrastructure without risking production uptime.
Rule Base Inspection & Cleanup
Identify shadowed, redundant, unused, and overly permissive any-to-any rules across industrial firewalls.
Least-Privilege Access Enforcement
Refine access control lists to only permit verified industrial protocols and designated host communication.
Deep Packet Inspection (DPI) Review
Audit application-layer protocol inspection for Modbus, CIP, PROFINET, and DNP3 to block unauthorized commands.
Performance & Failover Optimization
Review hardware resource utilization, failover configurations, and high-availability synchronization.
Non-Disruptive Migration Roadmap
Provide step-by-step rule migration plans that eliminate security holes without disrupting active operations.
Protect your infrastructure from evolving threats.
Comprehensive review and optimization of your industrial firewall rulesets.
Proven 4-Stage Methodology for Firewall Assessment
Our structured engineering methodology is designed specifically for operational technology and industrial control environments. Every phase is executed passively with strict change governance, ensuring zero disruption to live manufacturing and continuous compliance with IEC 62443.
Configuration Extraction
Exporting configuration files, NAT tables, and security policies from industrial firewalls safely.
Rulebase Audit
Auditing rule bases to identify overly permissive any/any policies, shadowed rules, and obsolete exceptions.
Rulebase Optimization
Restructuring rule sets around functional asset groups and Purdue zones to improve throughput and security.
Phased Migration
Delivering a staged change-management playbook for deploying optimized rules during maintenance windows.
Who Benefits Most From This Engagement?
Engineered for plant operations, control systems engineers, and cybersecurity leaders responsible for operational resilience.
Network & Perimeter Administrators
Need to clean up legacy any-to-any rules, shadowed configurations, and unmanaged access lists across industrial firewalls.
Industrial Cybersecurity Engineers
Must verify Deep Packet Inspection (DPI) enforcement for Modbus, CIP, and PROFINET against unauthorized commands.
Compliance & Audit Teams
Require documented evidence of least-privilege access rules protecting critical operational zones.
